About VoiceBench

A comprehensive benchmark for LLM-based voice assistants across 9 evaluation datasets, covering diverse speaker characteristics, environmental factors, and content variations. To submit your model, open an issue on GitHub.

Architecture types: Cascaded = separate ASR + LLM pipeline · Audio-LLM = audio encoder fused with LLM, text output only · Vision+Audio+LLM = vision & audio encoders fused with LLM, text output · Omni = end-to-end speech-in speech-out, turn-based · S2S / Full-Duplex = simultaneous listen & speak, no external VAD
